Overview

Mycobacterium malmoense (M. malmoense) is a bacterium naturally found in the environment, such as in wet soil, house dust, water, dairy products, domestic and wild animals, food, and human waste.[1][2] M. malmoense infections most often occur in adults with lung disease, and manifests as a lung infection.[3][4] Skin and tissue infections with M. malmoense have also been described.[1] In young children, M. Malmoense may cause an infection of lymphnodes in the neck (i.e., cervical lymphadenitis).[1][4]
